' V 24 Claims. 191-133) This invention relates, in general, to recording machines, such as typewriting machines, adding machines provided with printing mechanism, and the like, and with respect to its more specific features, to apparatus for the control and disposition of the continuous or long strips of supply paper frequently used in such machines.

Among the objects of the invention is the provision of practical and efiicient instrumentalities for effecting various improved results, as for instance, wherewith long, continuous, paper strips supplied to the machines mentioned may be shifted laterally in unison with the lateral shift of the paper feed devices so as, as much as possible, to avoid fanning or lateral shift of the superposed paper supply strips relative to each other; wherewith the container and the guides for the paper supply may readily and quickly be detached from the recordingmachine when it is not desired to use it; wherewith the force of the shock or recoil due to forcible movements of the paper-shifting devices, or to a great weight of supply paper, is cushioned, or these effects absorbed in a gradual manner so as not injuriously to shock and vibrate the machine; wherewith the injurious or shock effect of the operators violently thrusting'the paper carriage of a typewriting machine to the right in preparation for writing a new line is minimized, if not entirely eliminatedj wherewith the guiding of the paper from the supply point to the typewriting machine is facilitated and rendered more practical, and wherewith the paper supply container is adapted to accommodate paper supplies of various dif- 5 ferent widths. Withal, the object includes the provision of a simple and inexpensive construction of apparatus, which will \be strong and rugged, preferably all parts being of metal.

Other objects of the invention will in part be 40 obvious and will in part appear hereinafter.

The invention accordingly comprises the features of construction, combinations of elements, and arrangement of parts, which will be exemplified in the construction hereinafter set 45 forth and the scope of the application of which will be indicated in the claims. 1 t

For a fuller understanding of the nature and objects of the invention, reference should be had to the following detailed description taken in con- 50 nection, with the accompanying drawings, in

which.

Fig. 1 is a side elevation illustrating an embodiment of the invention, the paper supply container being shown associated with a type- 55 writing machine of standard construction, said machine being illustrated in a diagrammatic manner;

Fig. 2 is a plan view of Fig. 1, the platen of the typewriting machine being shown more in detail, and a part of the keyboard also appearing; 5

Fig. 3 is an enlarged, side view, partly in section, of the paper supply container and its associated supports and shifting devices, as appearing at the right in Fig. 1;

Fig. 4 is a plan view of a detail of Fig. 3, show- 10 ing one of the rails and its associated anti-friction rollers;

Fig. 5 is a fragmentary view looking at the left of Fig. 3, and illustrating the actuating block which is mounted on the container, and through 15 which shift movement is imparted to the container; and

Fig. 6 is a plan view illustrating paper guides, or brackets, one of which is disposed at each end of the receiving compartment of the supply con- 20 tainer;

Fig. 7 is a perspective view partially fragmentary of the device as assembled.

Referring now more specifically to the drawings, it is observed that the supply-controlling 25 devices are suitable for use with various machines, but are herein illustrated in connection with a standard form of typewriting machine, the frame of this latter machine being generally indicated by the numeral I. The numeral 2 indi- 30 cates the platen carriage which is shiftable in letter-spacing direction, as usual in typewriting machines, and the numeral 3 indicates the platen journaled in the platen support 4, this support being reciprocally shiftable up and down, that is, in case-changing direction, by use of the shift key 5 of the keyboard. The platen support 4 is mounted on the platen carriage 6, and the up and down shift of the platen is effected through the instrumentaiity of the usual lift hooks I (only one of which is shown), which are actuated from the key 5 through the lift-hook rod 8. All these parts may be as usually appear in standard Underwood typewriters and need not be further described.

Referring to Fig. 1, the record paper to be written upon by the machine is illustrated at 9. This paper may consist of a single, long, continuous strip, zigzag folded so as to form-a compact supply pack, as indicated at in, from which pack the paper strip is led beneath the platen of the typewriting machine. But it is to be understood that the suppiy may consist of a number of super-- posed record strips, with'or without long, continuous, carbon strips. When a plurality of the continuous strips, including continuous carbon strips, is employed, their advance ends. are entered beneath the platen and coact therewith to be fed in line-spacing direction by rotation of the platen. In so far as the manipulations by the typist are concerned, it is to be understood that the operations of typing and of line-spacing, and of letter-spacing and shifting the platen and the platen carriage, are similar to standard practice, and may be as exhibited in standard typewriting machines, or as exhibited in other recording machines.

At the rear of the typewriting machine is the paper-shifter membergenerally indicated by the letter A. This paper-shifter member is mounted for reciprocal shift movement in letter-spacing direction and, in the embodiment illustrated, includes a paper container, receptacle or supply container, into which the supply of paper may be introduced, as illustrated in Fig. 1. Specifically, in the present embodiment, the paper-shifter member includes a shiftable carrier frame of cradle-like design. In the embodiment illustrated, this carrier-frame is composed of two parallel angle bars l5 and I6, connected by cross bars I! and I8, to form a skeleton, cradle-like frame. Aflixed to this carrier-frame is the paper container proper which, in the embodiment il-ustrated, is of generally U-shape, and is formed of foraminous material. 7

Referring to Fig. 3, the paper container is made of light, perforated sheet metal, bent in a generally U-shape, to form the bottom wall I 9 and the side walls 23 and 2i integral with the bottom wall. This U-shaped container is removably fixed to the bars I5 and I6 by the screws 22. In order that the paper container may accommodate supply paper strips of various different widths. and indeed widths which are even wider than the longitudinal dimension of the U-shaped container, the opposite ends of the container -may be left open, and the paper guides 23 may be disposed at the opposite ends of the container. These guides consist of guide bars 23,

each having a handle 24 and two legs 25. These.

bars 23 are mounted between the limbs, or sides, 20 and 2| of the U-shaped container, and are adjustable toward and from each other. To this end, the sides 23 and 2| of the container are slotted as indicated at'26, and the guides 23 are supported on the container by screws 21 passing through the slots 26. Light plate springs 23 intervene the heads of the screws 21 and the container wall to develop some friction and prevent rattling. After the bars 23 have been adjusted to the desired position, they may be firmly secured in place by the thumb screw 29. These bars23 serve not only to guide the paper strip coming from the container, as illustrated, for instance, in Fig. 1, but they may be adjusted so as to dispose the supply of paper more to one side of the center of the container than to the other, or vice versa. The distance between the opposite guide bars 23 may be adjusted to less than the length of the U-shaped walls, or they may be disposed a greater distance apart to accommodate supplies of such -a width as to project through the opposite, open ends of the container.

Beneath the paper container is a base frame along which the container shifts. This base frame may rest upon the table, or other surface, alongside the typewriting machine, and ordinarily will be firmly secured at the rear of the typewriting machine. Like the container from the apices and connected by several cross bars .32, 33 and 34, to form a skeleton, cradlelike base frame, in which the paper container is received and supported for being shifted in letter-spacing direction and in unison with the platen of a typewriter. For directly supporting the paper container in the base frame, antifriction roller bearings, engaging rails or tracks, are employed.

In the embodiment illustrated, there are upper and lower parallel rails, the same being fastened to the base frame, one of these rails being the cylindrical bar 32 which forms a portion of the base frame, as hereinbefore mentioned. 'The other rail is a similar cylindrical bar 35 and is secured in position above the bar 34 of the base frame. The anti-friction bearings are mounted upon the container, being directly connected to the carrier frame I6, which forms a portion of the container. As illustrated, one anti-friction roller bearing 36 is joumaled on a stud 31, secured to an angle plate 38. s1idable to difl'erent adjusted pcsitions'beneath the carrier frame bar l1, and securable in adiusted position by a clamplng screw 33. Alongside the bearing roller 36 is another anti-friction roller 40 journaled on a stud 4| depending from a U-shaped bracket 42, the legs of this bracket being slidable to different adjusted positions on the carrier frame member l1, and being secured by screws 43. A number of anti-friction, roller-bearing units, each including a roller 33 and a roller 43, may be 7 utilized at a number of points in the length 'of' the container, the respective rollers in each unit being disposed at different points circumferentially of the rail 35, the roller 36 taking the vertical thrust of the weight of the container, the roller 40 being adapted to take any lateral thrust that may be developed.

For supporting the container on the upper rail 32, each angle bar l5 and I6 has a stud 44 on which a bearing roller 35 is journaled, these rollers each having annular grooves more or less intercepted by the circumference of the track rail 32, so as to have some resistance against a source of supply such as a roll, or a zigzag pack, to the feed device or platen of the recording machine, there is a tendency for the different strips to be displaced laterally, more or less, from each other, with the result that the printed forms of different superposed strips will be so much out of registry at the printing point that the inscription on the duplicates will not correspond in position on the printed form with the inscription on the original. This departure from registration tends to increase the greater the number of superposed strips employed.

Not only does this tendency to lateral displacement pertain to long, continuous strips by reason of the intervening reach of strip material between the bulk of the supply and the typewriting machine. The movement of the paper feed 7 typing operation or upon the return of the platen preparation for writing a new line, has the effect of twisting or prejudicially folding the continuous strips with consequent displacement therebetween, so that but little reliance upon the paper being fed in predetermined lines can be expected. On the contrary, the different strips of paper are displaced laterally from each other to a considerable extent. To the end of avoiding these objections as much as possible, and of improving registration at the printing point of superposed printed forms and of having the strips feed along predetermined lines, the present invention provides forishifting the paper strips in letter-spacing direction in unison with the platen of the machine, and it also provides for, as far as possible, avoiding relative displacement of different superposed paper strips, and possible injury or deleterious effect upon the machine or the printing by a substantial weight of the paper supply being used.

Between the platen carriage of the typewriting machine and the paper-shifter member hereinbefore mentioned, there are operative connections whereby shift of the platen carriage in letter-spacing direction causes shift of the paper container, or paper-shifter member, in unison therewith. In the present embodiment an actuating member, or block, 50 is coupled to the paper container and has shift movement relative to said container. As illustrated, the block 50 is mounted on a backing plate 5i fixed on the side wall 20 of the bent, foraminous plate composing the container proper. Projecting from the base plate 5| are two pins 52 and 53, preferably screws. Said actuating block 50 is of angular shape and has a flat portion 54 bearing againstthe base plate 5| and having a slot 55 through which the pins 52 and 53 loosely pass. Said pins have heads for retaining the actuating block 50 against the base plate 5|. Also, plate 50 has an opening, throat, or recess, 51, for being coupled or engaged with a block-driving member 58, hereinafter more particularly described.

Directly connected to be shifted in letter-spacing direction with the platen of the typewriting machine, is a connecting rod 59 which is directly supported by the platen carriage and extends in letter-spacing direction. The block-driving membert58 consists of an arm, one end of which is sleeved for longitudinal adjustment along the connecting rod 59, the other end of this arm being free for being loosely coupled to the actuating block 50 by entering the opening 51 in such block. A clamping screw 80 is utilized for securing the block-driving arm 58 in different adjusted positions on the connecting rod 59. For securing the connecting rod 59 to the platen carriage, two similar arms 6| are provided (only one of which is shown). Each of these arms has a split coupling 82, by means of which it may be securely fastened to the split collar (of the platen carriage), in which theli'ft hook rod 8 is journaled. It rav be noted at this point that the actuating devices coupling the container for reciprocal shift movement in letter-spacing direction by actuation of the platen carriage are connected to the platen carriage independently of the up and down case-shifting movement of the platen; that is, independently of platen shift which effects change from capitals to small letters, and the like. Anyadevice for coupling the connecting rod 59 to the platen carriage and which permits independent, vertical shift of the platen, is

within the purview of this part of the invention.

It will now be understood that as the platen shifts in letter-spacing direction, the connecting rod 59, and the block-shifting arm 58, shift in unison therewith and impart shift movement in letter-spacing direction to the actuating block 50, which latter, in turn, is adapted to communicate similar shift to the container in which the bulk supply of paper is placed.

This invention provides for cushioning movement, especially the final movements, of the paper container, and for lessening the shock on the platen carriage due to the paper container, which latter may be rather heavily weighted by reason of the bulk of supply paper therein. A device is provided which is adapted resiliently to arrest shift movement of the container at the end of its stroke, and which also cooperates to restrain relative movement between the paper container and the actuating block 58. To these and other ends, a spring is interposed between the paper container and the block 50. As illustrated, this spring is helical, one end being fast to the block 50 and the other end to the backing plate 5| on the container wall, the block 50.and container being thus resiliently but positively connected to each other.

It will also be observed that the extent of shift of the paper container, after arrest of its actuating mechanism, is limited. When the blockshifting arm 58 is arrested by arrest of the connecting rod 59 on the return stroke of the platen carriage, further movement of the container is gradually checked by the spring 65. If the spring 65 does not alone stop this further movement, the pin 52 will do so by abutting the end of slot 55 in the block 50, the end of the slot acting as a stop.

At the upper part of the side wall 20 of the container is a table on which the supply paper strips are supported as they pass to the platen.

This table consists of a, swinging plate 10, hinged at H to the side wall 20 and having legs 12 which may rest on the connecting rod 59 for supporting the paper table 10 in elevated position. The paper table 10 may be of foraminous inaterial forming a hinged flap of the side wall 20, although other material may be used. In superposed relation to the paper table are the lateral paper guides 13, the same being plates adjustable to different positions along the flap or table 10. The guides 13 are strung on rod 14, which latter is supported at its ends in ears or brackets 15. The brackets 15 and the legs 12 may be integral parts of a plate 16 secured to the underside of the table 10 by a'series of screws 11.

For steadying the paper container on the base frame, the carrier frame may be provided with one or more channel plates I8 secured at intervals to the underside of crossbar [1, the rail 35 lying partly in these channels.

For detachably securing the base frame to the typewriter or other machine, various different securing devices may be utilized. -As herein illustrated, sleeves or clevises 19 are engaged over frame member 80 of the typewriter, and secured in place by clamp screws 8|. Each side bar 38 and 3| of the base frame terminates in a standard or leg 82, having a slot 83, the leg being clamped in adjusted position to clevises 19 by separate clamp plate 84 and clamping screw 85. At 88 is a rubber foot or shoe for supporting the central portion of the base frame.

Whereas a container for receiving the supply of paper in bulk, as in a flat packet ID, from broader features of the invention contemplate the shifting laterally of the paper strips in uni- .son with the platen without the paper strips being disposed in a container. As to those features, it might be desirable to shift only reaches of strip between the platen and the supply pack, in which case the bulk of supply might rest in stationary position in rear of the typewriter.

The operation of the device will be largely obvious from the foregoing description, but brief reference thereto may be made.

It will be apparent that the base frame of the Paper supply apparatus may readily be attached and detached from the typewriting machine by merely manipulating the screws 8| and 85. It will also be perceived that by reason of the cradle-like shape of the base frame and the container, these two parts may be closely nested, the container in the base frame, so as to take up relatively small vertical space. Also, inasmuch as the cradle-like container'is largely suspended from the two tracks 32 and 35, the center of gravity of the container, and its load of supply, is relatively low and the apparatus thus rendered stable in marked degree. It will also be seen that the container including its carrier frame may be readily, removed from the base frame without any complicated manipulation, it being required only to disengage the block-driving arm 58 from the actuating block 50. Having placed a supply of zigzag folded paper strips en bloc in the foraminous container, as illustrated in Fig. 1, the advance ends of the paper strips are led across the paper table HI and assembled in operative feed relation with the platen 3. As typing progresses, the platen is shifted to the left by the mechanism of the typewriting machine. In unison therewith, and through the actuating members GI, 59, 58, 51 and spring 65, the container with its paper supply also is shifted to the left, moving easily in letter-spacing direction along the rails 32 and It will be noted that shift movement is imparted to the container through the spring 65,1118 shift actuation of the block 50 tending to elongate this spring. Ordinarily, a spring may be used which. when the apparatus is at rest, will cause the pin 53 to be in abutting relation with the end of the slot 55. Upon quickly thrusting the platen carriage to the right, as is usual in preparation for beginning a line of writing,

' the platen carriage will be positively arrested by the right-hand margin stop of the typewriter; also, the block-driving arm 58 will be as promptly arrested inasmuch as it is positively connected to the platen carriage.

But the container with its supply of paper strip may have a further movement to the right,

which movement will gradually be checked by the spring 65, and ultimately stopped by contact of the pin 52 with the end of the slot 55. Inasmuch as the load due to the paper container and the supply therein may be comparatively heavy, so as to have considerable momentum on its return movement'just mentioned, it is very desirable yieldingly to bring the paper carriage to rest, as by the spring 65, in order that the shock otherwise resultant from sudden arrest of this heavy load may not be imparted to the platen and platen-carrying parts of the typewriting machine. Furthermore, by bringing the paper con-,'

tainer gradually to rest, the paper supply and the reaches thereof extending from the container .to the platen are not stopped suddenly. Consequently, lateral registration of the'diiferent superposed paper strips is not apt to be disturbed.

By providing thepaper container walls with numerous round perforations, guide pins and aligning pins may be readily distributed at various difierent points for the purpose of guiding paper strips of difierent widths, and the like. In Fig. 7, the numerals indicate guide pins supported in-the apertures of'the paper table 10. The container is adapted for utilizing any practical width of paper that it is sought to use. Ordinarily, the container will be of a suitable size to accommodate paper of standard width for standard width platens. However, the container will readily accommodate widths of paper which overlap the open ends of the container, this widerpaper being steadied and retained by the paper guides 23. The paper guides I3 may be shifted along the paper table 10 to accommodate different widths of paper. It is observed that for supporting the paper table Ill, no part of the typewriting machine is required. Once the connecting rod 59 is secured in place, the paper table 10 may be upheld by the legs 12 resting upon this rod.

It is observed that roller 40 is slightly below the level of the center of rail 35 and underlies said rail to a small extent, when the container is suspended on the rails. Hence, rise of the container of the rail 35 is somewhat resisted by the underlying roller 40. But due to resiliency of the bracket .42, the roller 40 may be spnmg past the rail when desired.

Since certain changes may be made in the above construction and different embodiments of the invention could be made without'departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not ina limiting sense.
